Gasco Energy Announces Amended Credit Agreement

•   Borrowing Base to be Reduced to $16 million at April 1, 2010 from Proceeds of Midstream Sale
•   Requirement for Special Re-determination Eliminated
•   Company Immediately Commences Its 2010 Utah Well Completion Program

DENVER, February 2, 2010 /PRNewswire-FirstCall/ — Gasco Energy (NYSE Amex: GSX) today announced an amendment to its Credit Agreement led by JPMorgan.

Amended Credit Agreement

On February 1, 2010 Gasco entered into the Ninth Amendment to the Company’s Credit Agreement with the lenders (the “Lenders”) thereunder pursuant to which the Credit Agreement was amended, among other things, to no longer require special redeterminations of the Company’s borrowing base. Borrowing base redeterminations will now revert to the regular redetermination schedule of every six months on or about May 1 and November 1 each year. Additionally, the interest rate margin (as more fully described below) was increased by 0.25% effective February 1, 2010.

Furthermore, the Ninth Amendment includes a reduction of the Company’s borrowing base to $16 million from $35 million to be effective April 1, 2010. The Company anticipates using a portion of the expected $23 million in gross cash proceeds from its recently announced asset sales (expected to close in the first quarter of 2010) to repay the outstanding loans in an amount sufficient to conform to the reduced borrowing base. As of January 31, 2010, the Company had cash on hand of approximately $11 million and had outstanding borrowings under its credit facility of approximately $35 million.

Interest on borrowings under the Amended Credit Agreement accrues at variable interest rates at either, at Gasco’s election, a Eurodollar rate or an alternate base rate. The Eurodollar rate is calculated as LIBOR plus an applicable margin that varies from 2.75% (for periods in which the Company has utilized less than 50% of the borrowing base) to 3.75% (for periods in which the Company has utilized greater than 90% of the borrowing base). The alternate base rate is calculated as (1) the greater of (a) the Prime Rate, (b) the Federal Funds Effective Rate plus 2.00% or (c) the Adjusted LIBO Rate for a one month interest period on such day plus 1%, plus (2) an applicable margin that varies from 1.75% (for periods in which the Company has utilized less than 50% of the borrowing base) to 2.75% (for periods in which the Company has utilized greater than 90% of the borrowing base). Gasco elects the basis of the interest rate at the time of each borrowing; however, under certain circumstances, Gasco’s lender may require it to use the non-elected basis in the event the elected basis does not adequately and fairly reflect the cost of making such loans. In addition, Gasco is obligated to pay a commitment fee of 0.50% under the Credit Agreement quarterly in arrears based on a percentage multiplied by the daily amount that the aggregate commitments exceed borrowings under the agreement.

Management Comment

Commenting on Gasco’s Amended Credit Agreement, Gasco’s president and chief financial officer King Grant said: “The sale of our midstream asset will provide us with the financial flexibility to pay down a portion of our credit facility and return to the normal twice-yearly redetermination schedule. We are carrying a cash and equivalents balance of $11 million and, after applying a portion of the cash on hand and the anticipated proceeds from asset sales, expect to have approximately $10 million in borrowing availability under our credit facility at the end of the first quarter, allowing for continued development of our Riverbend project assets. Stronger natural gas prices in the Rockies, which we expect to continue through the winter heating season, provide attractive economics for us to begin re-completion operations in Utah immediately. We expect that flush natural gas production from these up-

hole zones will boost production and cash flow. Gasco has an inventory of 34 operated wells with up-hole recompletion opportunities and also have two Upper Mancos wells awaiting initial completion activities. We expect to have final Board approval for our 2010 capital budget in the coming weeks.”
